But as far as running hardened pet-friendly rentals in the ghetto goes -- solid hardwood flooring sealed and finished with three coats oil-based poly is undeniably the way to go if you want the most tenacious option you can get.We do tile in kitchens, bathrooms, foyers, and various utility areas, too.

In my experience, paint + primer-in-one is the biggest lie in home improvement, a close second to one-coat-coverage.My renovations are typically turning old, well-lived-in houses into hardened rentals.

Here's an old thread with hundreds of responses and many good ideas:  https://www.biggerpockets.com/forums/52/topics/68041-how-do-you-harden-your-rentals

It's just as hard to find good management, however, as it is to find a good tenant, so if you take the time to do the research and know your rights -- landlord/tenant, fair housing, screening tenants, hardening your rentals, etc., then you'll benefit moving forward.

So I'm going to get the paint hardener and use bagster. 

My partner in his infinite ignorance removed ALL the old grey hardened cement putty/caulk from the gaps to make it look nice.

There is no such thing as premixed thinset mortar, as cement-based mortar does not harden by drying, as mastic adhesives do.

I think dogs do more expensive damage than cats, but that's another topic.It's good business sense to harden your rentals against pet damage, even if the lease says no pets, and not to use $$$$per square yard carpeting in them.
